A federal judge in Miami Wednesday cast serious doubts about Gov. Rick Scott’s order requiring thousands of state government employees to undergo a random drug test, suggesting his policy “sweeps too broadly.”

U.S. District Judge Ursula Ungaro peppered a government lawyer with questions about the constitutionality of Scott’s policy, saying she had “trouble understanding the circumstances under which the executive order would be valid.”

Jesse Panuccio, deputy general counsel for Scott’s office, did not provide specific examples but rather talked generally about the harm of drug use among state employees in the workplace. “Drugs are very harmful,” he told the judge. “They’re very dangerous.”

Ungaro said she would soon make up her mind about the legal challenge to Scott’s policy by the American Civil Liberties Union of Florida. The group argues that his order violates the Fourth Amendment rights of state workers because the testing requirement is “suspicionless” and therefore an illegal search and seizure. Story here.
